Answer to Question #343186 in Physics for ELLE

Question #343186

Determine the amount of current needed by straight wire 60.0 cm long to generate a 70N force while being exposed on a 27.5 T magnetic field acting 90.0^(0) on the wire.

Expert's answer

"F=BIl\\sin\\theta"

"I=\\frac{F}{Bl\\sin\\theta}\\\\=\\frac{70.0}{27.5*0.600*\\sin90^\\circ}=4.24\\:\\rm A"
